I have a Cisco 1112 SACS device configured as Radius server, the SIP servers are added to the ACS as Radius clients for server key: ?key? under authenticate using I choose ?Radius-IETF? for both Radius clients.
I setup users on the SIP server as follow ?1? and ?2? just for testing for calling to and from each other?
ACS Interface configuration for Radius-IETF for the Default Group I checked Login-TCP-port under group configuration Radius-IETF Login-TCP-Port I use port ?1812?.
On the ACS I setup users as follow ?1? and ?2? and the user configuration for both users are as followed Password Authentication: Cisco Secure Database and add the user to the default group.
My problem is when I call from phone 1 to phone 2 I get the message ?Authentication failed? up on checking the ACS failed log I can see the ACS communicating with both SIPS I also see the message ?Bad request from NAS?
Can anyone say what I?m missing and/or what I need to do so the ACS can authenticate the SIP request??
All I wan to accomplish is when the SIP sends a request to the ACS to check if the user is setup the ACS authenticate the user and sends the authorization response back to the SIPS.
Any help is appreciated.
